CNC Cylindrical Grinding Services
Precision Cylindrical Grinding for Difficult Alloys: Achieve ±0.002 mm Tolerances
When your components require exact bearing fits, flawless sealing surfaces, or precise concentricity, standard turning is rarely enough. At AXALLOY Precision, we provide CNC cylindrical grinding services specifically tailored for difficult-to-machine alloys.
We support engineering, procurement, and quality teams by transforming raw materials like Inconel, Titanium, and hardened Stainless Steels into high-value, tight-tolerance components. Whether you are validating a new aerospace prototype or setting up repeat low-volume production for medical devices, we deliver the process control and documentation you need to assemble with confidence.

We do not just remove material; we engineer the grinding process based on your material's behavior, geometry, and final application. Here is exactly what our capabilities mean for your project:
-
1
Interference-Free Assembly
By holding diameter tolerances down to ±0.002 mm and cylindricity to 0.003 mm, we ensure your shafts, pins, and sleeves slide into bearings or housings exactly as designed, eliminating costly manual fitting on your assembly line.
-
2
Leak-Proof Sealing Surfaces
We achieve surface finishes down to Ra 0.2 μm. For fluid control, oil & gas, or hydraulic applications, this mirror-like finish guarantees optimal O-ring seating and prevents pressure leaks.
-
3
Zero Thermal Damage on Hard Metals
Grinding superalloys generates intense heat. We control wheel selection, feed rates, and coolant application to prevent surface burning, micro-cracking, or warping in heat-sensitive materials like Titanium and Nitinol.
-
4
Reduced Supply Chain Risk
By combining CNC turning, milling, and cylindrical grinding under one roof, we take full responsibility for the finished part. You avoid the delays and quality risks of moving parts between multiple specialized vendors.
How Predictable Lead Times Protect Your Schedule
We understand that in advanced manufacturing, a late part can stall an entire system build. We don't just promise "fast delivery"—we structure our production to actively protect your timeline:
Prototype Lead Times
5–10 Business Days
Getting ground prototypes in your hands quickly means your engineering team can perform physical design validation, test wear resistance, and lock in the final design without losing weeks in the development cycle.
Standard Production
10–20 Business Days
For low-volume and batch production (20 to 10,000+ parts), our controlled scheduling ensures your procurement team avoids line-down situations. You receive a steady, reliable supply of critical components exactly when your assembly schedule demands them.
